Para encontrar la constante de proporcionalidad, podemos usar la relación entre la cantidad de sal comprada y el costo. La constante de proporcionalidad (k) está dada por la relación entre el costo (y) y la cantidad de sal (x), es decir, k = y/x. Dado: 1 kg de sal cuesta 12 pesos. 4 kg de sal cuestan 48 pesos. 9 kg de sal cuestan 100 pesos. Podemos usar la información proporcionada para encontrar la constante de proporcionalidad (k) estableciendo la ecuación de proporcionalidad: Por 1 kg: 12 = 1k Para 4 kg: 48 = 4k Para 9 kg: 100 = 9k Resolviendo para k en cada caso: Por 1 kg: k = 12/1 = 12 Para 4 kg: k = 48/4 = 12 Para 9 kg: k = 100/9 ≈ 11,11 La constante de proporcionalidad es de aproximadamente 12 pesos por kilogramo de sal.
